Hi, Sounds like non apple memory in G4. remove memory to a single stick of 128 meg and try again. If that don't work, reset pram. Suspect that you have a slight flaw in memory- won't affect day to day stuff, but install disks are really touchy about installing OS10.4 <url>http://www.forevermac.com</url>for all your Refurbed mac kit in the UK

On old macs it seems almost impossible to read the 'new' DVDs that are packaged with copies of 10.4 retail boxes. The Cube (2001) is one such model. it gives errors over and over again. Once you attach a 'new' ie modern DVD reader via firewire, bingo, it installs first time, no probs.
